Deliverable: a still-frame prompt per segment + a ~4s video prompt(a one-line metaphor may be attached).
Default Written Specs
16:9 · about 4s per segment · H3 · collage SFX only · no BGM/voiceover/subtitles (unless the user specifies otherwise)
Style Signature (shared by image/video)
flat bold color field, black-and-white half-tone photographic cut-outs,
selective colored cardstock accents, warm cream keylines, soft paper shadows,
fine uncoated-paper grain, premium editorial paper collage,
clean hand-torn edges, layered paper seams
Rule sentence: clear foreground/midground/background; 3–6 large paper-piece groups; paper neither too flat nor too dirty-brown;no readable text/fake UI/logo。
Draft: one metaphor per node
Core meaning · emotion · 3–6 objects · color field · assembly order · SFX points
Still-frame prompt (completed state = final frame of the animation)
Meaning + style signature + objects and layers + color field + no text/no UI
Video prompt (stop-motion assembly)
Paper-collage stop-motion assembly. Start on clean paper field matching the still.
Piece by piece: appear → slide/pop in → light bounce → press flat → pause → lock.
Preserve half-tone, cream keylines, torn edges, seams, soft shadows, {画幅}.
End holding the approved still composition.
Sound: tactile collage SFX only, synced to paper motion.
No BGM/VO/subs unless requested. No kraft mismatch open, no chaotic flight,
no smooth digital pans, no cuts/zoom/morph, no text/logos/UI.
You can use the still frame as an anchor following the I2VA/FL2VA approach (see h3-prompt-writing）。
Self-check
- The metaphor is understandable without text
- Piece-by-piece assembly, not a whole-image fade-in
- Opening color = still frame; final frame matches the still frame
- By default, collage SFX only
